FEED-THROUGH SWITCH.

Specicaton of Letters Patent. PatQnted Oct. '12, 1920.

Application lled March 13, 1918. Serial No. 222,072.

To @ZZ whom it may concern:

Be it known that I, RALPH A. BELMONT, of New York, in the county andState of New York7 have invented a new and useful Feed-Through Switch,of which the following is a specication.

A feature of my invention is that the switch is mounted on a supportwhich is separate from the casing, one of the advantages of thisconstruction being that if the switch burns out the casing is stillavailable for use and another of the advantages being that the wiring isvery easily done, the wires being connected to the support' and then thecasing applied.

Another feature of my invention is a casing which is split; preferablylongitudinally, and which surrounds the switch and is held thereto.

Another feature consists in fastening means at both end s of the casingand preferably I use means which can be snapped in place, such as splitrings. i

Another feature consists inl providing a neck or necks to surround theconductors, the neck or necks preferably cooperating with thefasteningmeans. Y"

Other features will be pointed out Qelow.

Figure l is a plan of my switch with the casing applied;

Fig. 2 is 'a plan with one casing member Fig. 3 isa reverse plan ingmember removed; y Fig. 4 isa plan of the support;

Fig. 5 is a central vertical section;

F ig. 6 isa vertical section on line 6--6 of Fig 3; .I t y Fig. 7 is aplan of the movable contact;

Fig. 8is an elevation of the movable contact; and f 'Fig 9 is anelevation of the' Vswitch with the casingapplied..

4The supportAffor the iixed and movable contacts is a Isubstantiallycylindrical block of porcelain or other vinsulating material cut awayatja and a so as not to interfere with the pushbutt/xons and also havingdepressions a2 and a?" adjacent to the fixed contact screwheadshereinafter described so as to permit the ends fof thel movablecontact to sink slightly. asthey approach the fixed contacts and thusmake a very efficient contact. Support A` has a recess to. receive ametal plate with the other casscrew acting as a fixed contact.

- ber H is crimped at L and h2 to ends great resiliency so that theywill eili- B which'has a wall at one end having an upper portion b 'anda lower portion b, these portions being spaced to receive the actuatingbar hereinafter described. At the other end of the plate is a similarwall having-up- -per portion b2 and lower portion b3. The

metalplate has a slot b4 and holes b5, b and o7 to coperate with otherparts described below, holes b5 and o7 being threaded. On the reverseface of support A are depressions d and d to receive the heads of screwsD and D', which screws pass through the support, the former engagingthreaded hole b5 and the latter engaging threaded. hole 57 to hold themetal plate B in place. The reverse face of the support is depressed atd2 to permit ready manipulation of wire E in attaching the latter to thebinding post E which is carried by plate E2, the latter being held inplace by means of threaded connection with the shank f of a screw whichpasses through the support or base A, the head F of the Similarly thereverse face is depressed at d3 for manipulation of wire G in attachingthe latter to binding post G which is carried by plate G2, the latterbeing held in place by means of threaded connection with the shank g ofanother screw which passes through the support, the head g acting as theother fixed contact. 4

The movable contact member H has a stud riveted to it the shank h ofwhich enters hole be vand acts as a pivot for the member H. Near thecontact ends the memgive the ciently engage .the xed contacts.

The push buttons K and K are cut away as shown so as' not to strike thesupport and they are mounted .on the ends' of bar K2 which is guidedbetween'theupper portions b and b2v and the lower portions lb and b3,said bar being provided with depending lugs 7c and. k which engage thewalls of the metal plate B' to limit .the movement of the bar K2.

A coiled bow spring M has one.end m passing through themovable Contactmember and, hooked or bent 'thereunder the -Yhooked portion riding inslot b4. The other end m ofthe spring is curved around and hooked intothe bar K2 and when the bar Kz is pushed upward in Fig- 3 end m of thesprmg is carried upward and when said end v-movable contact will beactuated out of engagement with the fixed contacts and the reversemovement of the bar K2- Will givev reverse movement to the movablecontact. i It will be clear that .the lined and movable contacts aremounted on the support or base and the wires E and G connected thereto,the wire N resting along the edge of the support, the structure thusforming a complete entity apai't from the casing which is splitVlongitudinally to form two members P and P, the flat face p of member'Pengaging the flat face p of member P. Member P has a neck portion 292 atone end and 'p3 at the other end, member P having similar neck portionsp4 and p5, the portions p2 and p5 coperating to surround the conductorsat one end. of the device while the portions 273 and p* coperate'tosurround the conductors at theother end of the device. Member P isgrooved at p and 29T-to receive the split rings described below and hasa deep recess pff to receive the springM and has also a raised circularrib p toenter member l/ so as to prevent relative movement of face palong face p other than ro tary movement. Member P is grooved at p10 andp11 to receive said split rings and has recess p12 to hold the supportagainst sidewise or lengthwise movement and additional recesses p13 andplt to receive the binding posts, space p15 in Fig. 3 receiving the ribp9. y

lVhen the switch parts and the wires have been attached to the supportas a separate entity the two parts of the casing arel applied and thesplit rings R and R are snapped into the grooves of members P and P tohold said members together, the portions ;01 and p oi' rib 71.9 byengagementV with wires'E and G tending to prevent removalof the supportfrom recess p12,

What I claim is:

l, A device of the character described comprising afbase of insulatingmaterial;

I therewith.

cludingterminalsare mounted on said base; a longitudinally split casing-for said elements comprising a plurality of parts of insulatingmaterial, said switch mechanism" itself being entirely disconnected fromsaid casing; means to hold said parts of theca sing together; anelectrical conductor con-' nected to one of said terminalsanother'electrical conductor` connected to the other of saidterminals;and athird electrical conductor passing through said casing. f

2. A device of thel character described comprising a base of insulatingmaterial;

switch mechanism,' all of whose parts including terminals are mounted onsaid base; a longitudinally split casing for said base and switchmechanism and comprisingv a plurality of parts of insulating material,

3. A device of the character described` comprising abase of insulatingmaterial; a-

switch mechanism, all of whose parts including terminals Aare* mountedonv said base; a longitudinally split casing for said base and switchmechanism and comprising. a plural-l ity ofparts of insulatingvmaterial, neither said base nor any part of said switch nechfanism'having any iXed connection with said -casing but being held inplace by vsaid cas* ing; lmeans to hold said parts of the casingtogether; an electrical conductor connected to one of said terminals;another electrical yconductor `connected to` the other of saidterminals; and a third electrical conductor which is flexible andcovered with insulatingv material and which passes entirely through saidcasing'but has no fixedbonnectior RLPH A.
